KocksMeckingActivationEnergy

Source: models/solid_mechanics/plasticity/KocksMeckingActivationEnergy.py

Calculates the Kocks-Mecking normalized activation as \(g = \frac{kT}{\mu b^3} \log \frac{\dot{\varepsilon}_0}{\dot{\varepsilon}}\) with \(\mu\) the shear modulus, \(k\) the Boltzmann constant, \(T\) the absolute temperature, \(b\) the Burgers vector length, \(\dot{\varepsilon}_0\) a reference strain rate, and \(\dot{\varepsilon}\) the current strain rate.
